Key:2|8=28 years
To find the median age, we need to find the middle value in the set.
The ages are: 28, 31, 32, 34, 37, 39, and 54
Since there are 7 values in the set, the middle value would be the 4th value in ascending order.
The 4th value in ascending order is 34.
So, the median age is 34 years.
